Penny black 1990 Royal Mail PNC

[SilverPebble]

Hi all and thanks for taking the time to read this

I was given a 1990 penny black Royal Mail PNC and I'm trying to find out if the coin is .925 silver I do know that the Royal Mail issue silver coin PNC packs

The pack came with 6 double headed stamps at 20p and a COA but no information on the coin I've spent the last 2 weeks scanning the Internet trying to find information and I've also emailed the company that sold the pack and I've hit a brick wall

If anybody can help please post below

If it the pobjoy mint coin?  Does it read 'Isle Of Man' on the obverse?

I have recently bought the reissue of the coin but I have put it away and don't have it here.

 

As far as I know the 1990 was issued in both silver and cupro nickel.

 

Here is a link of the cupro nickel

The silver version is hard to find but here is the rerelease.

I wonder whether you can weigh it.

It does look fairly similar to my one pictured here:

the cupro nickel should be thicker or the silver

one have a high rim. it'll be hard to tell when it's

in the packaging with nothing to compare against.

stupidly, mints do this frequently, they should just

stamp 925 on the edge.

I just read this on using magnets on cupro nickel and found this great line.

For silver coin:

U can blow a silver coin and put it next to your ear, hear clear vibrating sound? - that is silver. Traditional Chinese way...

Who needs a ping test app?

I can't do the magnet test with destroying the packaging

Here is a completed ebay listed in which they have it as silver proof.

Their images show some extra text too. Maybe you have that on the back of the card.

[SilverPebble]

That's the same one I've got with text on the back

Magnet test will still work through the packaging

try moving the magnet to try and pull against

the coin through the packaging. magnets won't

stick to silver or cupro nickel. so you need to

constantly move the magnet across the surface

of the coin and feel the resistance to movement

that it gives. silver gives a much stronger tug.

you can gauge this by trying the same thing on

another silver coin. try and avoid using 0.500

junk silver as they give inconsistent results.

No the magnet test doesn't work as the plastic is to thick

[daz]

Are you using a neodymium magnet or a normal magnet ? If you slant the coin at 45 degrees and place the neodymium magnet on tne coin you can notice the slight pull by the magnet slowly sliding even through thick hard plastic coin capsules. If the magnet test is not working through that packaging I would guess its not silver

[SilverPebble]

I used a neodymium magnet again and there's no pull at all or none that I can see
